Working Theory

A popular alteration amongst vehicle owners is to decat the exhaust system or install an aftermarket header, to unleash the HP of the vehicle. Nowadays, exhaust gas is controlled through two to up to four exhaust o2 sensors, at least one front sensor that controls the fuel management system, and at least one downstream that monitors cat function. When the aftermarket headers are installed or converters are removed on your Opel Sintra, the result is a catalyst efficiency check engine light CEL code alerting the ECU that the catalyst is missing or not working properly. The modified engine now produces a larger amount of exhaust gases than allowed. Obviously you do not want to drive your car with a constant engine management warning light, in addition your Opel Sintra will not pass smog test in many US states or countries with an illuminated check engine light. The ultimate solution is to install an O2 sensor simulator wired up to the aftercat exhaust oxygen sensor’s harness in order to simulate a properly functioning air fuel sensor. EZ CEL Fix oxygen sensor eliminator outputs the Engine management with mimicked, fluctuating voltage signal and tricks the Electronic Engine Management into thinking the emissions are within permitted range. Your Opel Sintra oxygen sensor simulator will allow you to drive your vehicle without catalyst and still keep the check engine light off.

This unit eliminates 1 up to 4-wire narrowband oxygen sensors only.

When check the engine light is triggered, the engine runs in ECM safe / limp mode, which results in sluggish acceleration and spoiled fuel mileage. EZ CEL Fix O2 Sensor Simulator eliminates either front or aftercat sensor, thus you can remedy the frustrating check engine codes. Magnum EZ CEL Fix Oxygen sensor simulator is available to all cars, trucks and SUV's fitted with 1 up to 4-wire narrowband zirconia air fuel sensors functioning in the standard 0 up to 1.0 Volt fluctuating voltage range. Feel free to contact our engineers prior to purchase, if you are unsure about your Opel Sintra's lambda sensor type. EZ CEL Fix Oxygen sensor simulator remedies all catalyst efficiency and oxygen sensor related error codes caused by alterations made to your Opel Sintra’s exhaust. Dual exhaust with two aftercat oxygen sensors requires two EZ CEL Fix eliminators. This Opel Sintra O2 Sensor Simulator is adjustable, making you enable to adjust the Air Fuel Ratio within certain range yet complies with the requirement of Engine management.

Notes

In case of a single oxygen sensor or dual pipe exhaust system fitted with two air fuel sensors only, the oxygen sensor simulator connects to these ports.

Headers require both up- and downstream Oxygen Sensor elimination.

frontexhaust o2 sensor has to work flawlessly. Slow signal of precat oxygen sensor may prevent the downstream oxygen sensor emulator from working.

Oxygen sensor simulator is a racing part. It is not CARB approved. Please be aware of the bylaws and regulations, O2 sensor eliminator is not street legal in several US states and countries.

Opel Sintra EZ CEL Fix Oxygen Sensor Simulator is a must-have device if you are about remove the converter or even if you installed aftermarket header, a performance catback system or high flow converter. Are you chasing after the ultimate solution for engine management warning light issue? Then you’ve come to the right place.

Don’t want to waste your time installing oxygen sensor bypass gadgets that will never rid you of the service engine soon light for good? Choose the reliable solution that will definitely cease your MIL light issue right away. EZ CEL Fix oxygen sensor simulator is made to prevent the SES light from illuminating and to prevent an PCM code from tripping when the catalytic converter is gutted or a header installed.

How can I figure out my sensor is a zirconia type?

Zirconia type oxygen sensors have 1 to 4 wires. 1 to 3 wires indicate a zirconia narrowband O2 sensor definitely. In the case of 4 wires, two of the wires have to be identical for heater, whilst the rest two wires have to be different for signal sender and signal ground. Always reference the sensor-side colors of the wires coming out off of sensor head. ECU-side colors may convert through the plugs.

How to find out if it's a narrowband or wideband?

Typically 1 to 4-wire sensors are narrowband. There are exceptions though. A narrowband oxygen sensor's signal is constantly fluctuating in a range of 0 to 1.0 Volts depending on oxygen content in the exhaust gas. Any oxygen sensor that produces higher voltages, is determined to be a wideband oxygen sensor. Keep in mind, although a 4-wire O2 sensor can be wideband too, in common sense only 5 or 6-wire sensors are called wideband. If your sensor has more than 4-wires, oxygen sensor is not applicable.

Which sensor has to be tricked?

In general: the downstream but upstream has to work flawless in full range. If you intend to buy a simulator hence decatting, header or modified exhaust, the downstream sensor has to be fooled by all means. See position diagram .

Headers or precat gutting requires upstream simulator as well.

Questions and answers

- Can I be positive this chip fixes my CEL issue for good and all? - Yes, Magnum oxygen sensor simulator produces a random fluctuation having assigned with suitable cycle and wave accepted by the ECU. Rest assured, all oxygen sensor signal related codes will be gone. Upstream sensor if any has to be in good condition though. Please see prerequisites pertaining to sensor type and quantity of simulators. - What if I simply eliminate factory oxygen sensor? - Oxygen sensor removal will not remedy CEL issue. Suitable fluctuating signal is fundamental to be delivered by the ECU. Zero volt signal triggers another trouble code. - Why is it so important to cancel the trouble code? - While check engine light is on, ECU restricts the engine performance and vehicle is running in safe / limp mode. MPG is also affected negatively. - Do I need to buy a heated simulator or I can stick with this cheaper EZ CEL Fix? - If you can use the heater of the factory oxygen sensor(s), you may wire up this #795 EZ CEL Fix. Heated simulator #661 allows you to remove or eliminate the stock oxygen sensor completely. - What about 'oxygen sensor bungs' 'mini cats' or any other piggybacks are also supposed to sort our FI problems? - The market is teeming with physical gadgets aiming to fix CEL issues. Vast majority of them doesn't take effect on OBDII vehicles made after 1996. They often don't work even on early fuel injected cars. If your vehicle had been manufactured after 1996 or you drive an early model controlled by a sensitive ECU, these gadgets won't help. The definite solution is a circuit conditions realistic signal, as if a working oxygen sensor would be screwed in the factory exhaust. - Can I rally my two harnesses into one simulator? - No, simulators can't be spliced. Get rid of oxygen sensor related CEL issue yet today. Flat catalytic converter gutting or plain-tube decats will spoil low- and mid-end torque hence ruined engine flush due to inadequate exhaust back pressure and higher block temperature thus valves, cylinder head and other engine parts are constantly being exposed to undesired extra heat. True enough, maximum horsepower increases it still pertains to a higher RPM which perishes dynamic kick out acceleration throughout the RPM range, mostly on automatic vehicles, therefore to save money on fuel and enhance low and mid-end torque, highly recommended to install a reliable Decat . Plain decatting is judged unprofessional among serious tuners and enthusiasts. Injected gasoline engines controlled by Electronic Control Unit (ECU) or alias Electronic Control Management (ECM) have oxygen sensor or O2 sensors to measure the amount of oxygen contained in the exhaust gas. These sensors deliver the ECU fluctuating voltage according to the actual oxygen consistence of air fuel mixture. When exhaust system is decatted or heavily modified, ECU is reading an oxygen sensor signal being inconsistent with other engine sensor's signal, or signal is out of the range yet accepted, an O2 sensor-related trouble code will be triggered ending up in check engine light issue. CEL or MIL or FI errors abbreviate these failures. While check engine light is on, ECU runs in so called lean limp mode. Safe mode restricts both the fuel trim and the ignition timing and develops an overall limitation on performance, until problem diagnosed and resolved definitely. Therefore if you modified your engine with any upgrade causes the oxygen sensor deliver lower signal than normally, you need to wire up an Oxygen Sensor Simulator. Although your ECU will be tweaked, mixture's air fuel ratio still will remain incorrect hence decatting or any other exhaust modification. Simulators help you remedy CEL problems but will not achieve that basic remapping is crucial when decatting or modifying an exhaust. You might be interested in our further performance chips in order to boost engine horsepower, improve fuel efficiency or both at the same time. EVO-Tech and Dyno-Boost and Smart-Tune-X fuel controllers remaps the ECU in order to reprogram the engine management to the performance parts preinstalled on the vehicle. They boost the engine horsepower as well as improve fuel mileage. Magnum Tuning has been dealing with manufacture of performance upgrades since 1994. Our experience warrants peak performance, reliability perfect style. Simulators are made in Europe covered by 10-year warranty.

Wiring

Cut the harness of the oxygen sensor.

See colors operations of each wire in car wiring diagram or search for your combination in the table below.

Connect the proper wires with terminals or solder them in place. (Hydrochloric acid recommended if soldering.)

Contact the red cable of the red/black dual wire to the ignition feed + 12V, and the black to the engine frame or battery negative.

Mount the unit to any fixture as far from heat as possible. Lowest temp recommended.

Notes

Simulator is waterproof but not submersible.

Always insulate contacts!

Make sure, check engine light refers to a valid oxygen sensor related trouble code, other errors cannot be remedied with a simulator.

If necessary, reset the ECU before readjustment because ECU does not "forget" errors necessarily and check engine light might keep on illuminating after installation of the simulator.

The difference between front and post sensor’s voltage is also monitored. If deviation is excessive, an error code might be triggered on the downstream pier, even though the issue is not caused by the downstream sensor. Upstream sensor also can be slow or stuck, so downstream sensor has to be in mint condition.

Usually aftermarket header ruins the upstream oxygen sensor signal. If so, upstream sensor has to be eliminated as well.

Flat catalytic converter gutting or plain-tube decats will spoil low- and mid-end torque hence ruined engine flush due to inadequate exhaust back pressure and higher block temperature thus valves, cylinder head and other engine parts are constantly being exposed to undesired extra heat. True enough, maximum horsepower increases it still pertains to a higher RPM which perishes dynamic kick out acceleration throughout the RPM range, mostly on automatic vehicles, therefore to save money on fuel and enhance low and mid-end torque, highly recommended to install a reliable Decat .

Plain decatting is judged unprofessional among serious tuners and enthusiasts.

Although EZ CEL Fix makes you enable to adjust the air fuel ratio within a certain range, basically it is not intended to remap the fuel trim. If you are about to override the factory lean fuel programming or you want to optimize the potential of your exhaust upgrade, feel free to check out our fuel controllers .

EZ CEL Fix Oxygen sensor eliminator has to be powered on ignition feed DC 12V. Never connect hot wire to constant battery voltage. This wiring may lead to battery drainage also may fry the circuit.

Emission test result depends on the criteria of your local emissions inspection. Simulator is neither supposed to improve emissions spoiled by an aftermarket pipe or any other upgrade, nor restore factory emissions required for a smog inspection. It is solely intended to help you get rid of ECU safe mode triggered by check engine light issue. It will not allow you to preserve factory emissions level. Simulator tricks the computer delivering mimicked signal is accepted by the ECU but it can’t purify the fume electronically. Cat is intended to attain that physically. Even though restoring of ECU to normal mode from safe mode improves emissions partially, if converter is gutted, worn or defective, original emissions can be preserved by no means.

The simulator is waterproof but not submersible.

EZ CEL Fix’s signal is set to factory 0.9…0.95V top voltage. Don't adjust signal related screw#1 until CEL issue is resolved. Basically screw#1 should not be dialed unless you want to modify air fuel ratio. We don't bear responsibility for CEL shut down, if signal is not set to the top voltage above.

recommend this o2 sensor dummy

This is an awesome upgrade over other o2 eliminators and minicats that literally did nothing to my MIL error. I highly recommend this o2 sensor dummy over other brands. The instructions are helpful and it only takes about 10 minutes to really put this thing in. Just take note of how wires are oriented. It fits the Rainder with the 5.5 ltr engine. I would buy this again.

gee MIL’s gone

when i went to install the o2 bypass purchased to my RAM, original MIL codes were blown but new slow o2 sensor response codes triggered, i was on the edge losing my patience after a total of 6 emails exchanged with tech experts. i was told check front sensors despite i had downstream codes!! after i shifted to another mechanic i was totally red in the face because he replaced upstream o2 sensors and gee MIL’s gone. this product works as described ans I will recomend it to my tow truck felows.

turned off instantly

i forked over the money to buy a total of 4 simulators to my dual pipe CL500, hook up was a breeze and MIL turned off instantly, my only criticism on the wire length dose not allow you to drive hot wire to to the fuse box so you need extra labor and wire extension. In any other respect this is a must have if you gutted your cats.

Better performance with no CEL

Better performance with no CEL on and gas mileage seems to be improved. They installed fairly quickly and no adjustment needed. Product backed by real technical support. !Wow free shipping! Great to do business with.

set up was fairly easy

Shipped fast, set up was fairly easy, works as described on website but was disappointed with the lack of instructions to explain what changes to the settings would do for richer mix or performance boost. I guess if i was a mechanic I'd know, but I'm not.

elimination seems to be completed fine

wanted to try gutting the cat converter innards in it and see if that makes a difference, first impression was bad since my simulator was stuck in miami for a week or so and when i consulted instructions they were a way missing but figured how to connect wires and all in all elimination seems to be completed fine, keep in mind stock o2 senser has to stay connected 'cos this simulator is not heated
